W22 Line

The increasing demand for electrical energy to sustain global development requires consistent heavy investments in power supply generation. However, in addition to complex medium and long term planning, these investments rely on natural resources, which are becoming depleted due to constant pressures upon the environment. The best strategy, therefore, to maintain energy supply in the short term is to avoid wastage and increase energy efficiency. Electric motors play a major role in this strategy, since around 40% of global energy demand is estimated to be related to electric motor applications. Consequently, any initiatives to increase energy efficiency, by using high efficiency electric motors and frequency inverters, are to be welcomed, as they can make a real contribution to reductions in global energy demand.
At the same time as efficiency initiatives make an impact in traditional market sectors, the application of new technologies in emerging sectors is resulting in profound changes in the way that electric motors are applied and controlled. By integrating these changes together with the demands for increased energy efficiency, WEG has taken up the challenge and produced a new design of high efficiency motor, one that
exceeds the performance of the previous WEG’s W21 motor line, which is recognised worldwide for its quality, reliability and efficiency.
Using the latest generation of computerised tools, such as structural analysis software (finite element analysis) and computer fluid dynamics, as well as electrical design optimization software, an innovative – next generation – product has been developed: the W22 motor.
Several key objectives have been achieved in the design of the W22 motor:

  • Reduction of noise and vibration levels;
  • Increased energy efficiency and reduced thermal footprint;
  • Easy maintenance;
  • Compatibility with present & future generations of frequency inverters;
  • Flexible and modular design.
